Application fllcdlebruary 11, 1909. Serial No. 477,445.

To all whom it may concern:

Be it known that 1, Roy A. W1LSON,8. citizen of the United States,residin at Cavite, in the Province of'Gavite and Is and of Luzon, Philipinef Islands, have invented certain new an useful Improvements inDefibratin -Machines; and I do hereby declare the ollowing to be "afull, clear, and exact description of the invention, such as will enableothers skilled in the art'to which it appertains to make and use thesame.

1v y invention relates to defibratmg machines, in which travelingcarriagesconvey the fiber under, over or between knives, brushes, orboth beinga' specific improvement uponthe (ilillies defibrating machlneas shown in the Gillies application, Serial No. 404,402, filed Nov. 29,1907.

The objects of my invention areto provide a mechanical means for feedingthe hemp or other lant into the machine and to make this cedingautomatic, thus increasing the ca acity of the machine.

With these 0 jects in view, in invention consists in the construction ancombinations of parts, as hereinafter described and claimed.

In the accompanying drawin -Figure 1 shows part of one end of a defirating machine with m invention applied thereto. Fig. d is an en view ofthe same, the guiding and supporting rails bein shown in section. Fig. 8is a plan view 0 one of the grippers. 'ig. 4 is a section of the same onthe line 4-4 of Fig. 8. Fig. 5 is an on view of one of the grippers.

a represents the-frame of the machine provided with cross beams I),braces'o and guiding and supporting rails d which are curved at each endof the'machme and between which the wheels'e'of the gripping carriagerun, all as described in the ap l1-.

cation above referred to. These-whee s e are mounted on the cross beam20, which beam supports the grippers hereinafter referredjto'; As thepresent invention relates =havmg an end 6', sloping sides 7 and abotonly to -the feedin means the general'machine will; not be escribe 1In brackets== on the machine frame i is mounted-'ash'a t-h on the centerof "which is mountedz'the swinginglever i. .To'the the machi whichnormally holds the lever in the position shown in Fig. 1. Near its lowerend thislever is enlarged, as shown at It, the enlarged part beingprovided with an elongated perforation m, through which passes the pinor shaft 11, on which the feeders are mounted. This elongated erforationis provided so that the feeders, ereinafter described, may be moved backand forth in a straight-line, although the lever i swings around theshaft h. hese feeders, of which there are two, one for each grip er andlo cated on each side of the lever 1, each consist of a metal box 0,open at the rear and top and having sloping sides, as shown in Fig. 1,and-each provided with a sprin plate 1), attached to the back of the boxan aving its free end,-which is serrated, bearing upon the front edge ofthe box. The s ring 72 extends the'full width of the box. ach of theseboxes is mounted upon an upri ht arm or standard, as g, in which stanards the ends of the pin n are firmly secured. Made inte a1 with eachstandard g, or firmly attache thereto is a horizontal guide arm r, whichis slidabiy mounted in a perforated su port 21 fixed to the frame of themachine bolts 22. The end of the arm r is provi ed with a notch s.Pivotally mounted on the pin t, carried by one of the guide rails d is ari ht-angled trip having a vertical arm u an a horizontal arm 4), aspring up being attached to the frame and to the arm v. or representsanother trip fixed to the support 21, the distance between said tripsbe1n nearly the same as the length of one o the carriages carrying thegrippers. These grippers, of which there aretwo on each carriage areshown enlarged in Figs. 3 and 4. ach consists of a shank 2 having ascrew threaded end 3, adapted to'be secured by a nut 4 to a cross beam'-20'-on the front of the carriage, and

having a-spline groove 5, to prevent the g'rippfr from. twisting). Atone end the shut terminates in a ox-like construction t0m'8, cut-awe asshown at 9'. The top and one'end o the box are open. In the sidesisfirmly secured a pin 10, on which is freely mounted a plate 11, havingan upwardly projecting portion 12 and eyes 13, to which spr ngs 1 areattached, the other Patented Sept. 3, 1912. i
